(Cl. 13B- 45) 7Claims. l

This invention relates to pipe couplings, one of l' the objects being toproduce a coupling device whereby adjacent pipe sections can be easilyand quickly forced toward and away from each other. More specificallystated, an object is to forcibly open and close a space between two pipesections, without actually disconnecting the pipe sections, whileproviding for quick removal and replacemeni-l of articles desiredbetween said pipe sections. For example, an old gasket may be quicklyremoved and replaced by a new gasket. However, this merely suggests thegeneral concept.

A separate and distinct object is to conveniently arrange for variationsin orices between the connected pipe sections.

A further separate and distinct value of the invention appears in therapid insertion of a blind closure member,- so as to promptly closecommunication between two pipe sections.

With the foregoing and other objects in view, the invention comprisesthe speciilc combination and arrangement of details herein shown anddescribed to illustrate features `of the invention. However, it is to beunderstoodv that the scope of this invention extends to variations andmodifications described by claims hereunto appended. f

Fig. 9 is an edge view of said operating ring.

Fig. 10 is a View ofA said ring showing the side face opposite to thatshown in Fis. 8.

Fig'. 11 illustrates a gasket suitable for use between the pipesections.

' Fig. 12 shows-an orice member having holes of diilerent diameters.

Fig. 13 shows the gasket of Fig. l1 applied to said orifice member. f Y,

Fig. 14 is a vertical section showing gaskets at opposite sides of theorifice member.

Fig. 15 is a view similar to Fig. 12, illustrating another form of thisldetail.

Fig. 16 is a fragmentary longitudinal section showing an arrangement ofby-pass pipes at opposite sides of the orifice member.

Fig. 1'1 is a diagram of a condition which appears when said by-passpipes are connected to an orifice meter.

Fig. 18 is a diagram of another form wherein the by-pass pipes are morewidely separated from each other.

The housing herein vshown comprises an elongated housing member A, and ashorter closure member B united by means of screws i9, as shown inFigures 1 and 3. These members A and B have iianges to receive theconnecting screws iii.`

To illustrate suitable pipe sections extending from the housing we haveshown a pipe section 20 formed integral withthe housing member B,

and a pipe ksection 2| slidable in the housing member A. y

A removable sealing device C is interposed between these pipe sections2li and 2i, so as to seal the pipe coupling when the slidable pipesection 2i is forced toward its companion pipe section 20.

Assuming that the sealing device C includes a gasket of any suitabletype, it may be noted that the coupling will be sealed when the slidablepipe section 2i is shifted from the position shown in Fig. 3 to theclosed position shown in Fig. 4.

The means for detachably clamping said gasket, or sealing device,between the pipe sections comprises an oscillatory operating ring Dsurrounding a neck 22 of the slidable pipe section 2i. This slidablepipe section 2i is provided with separated iianges 23 having cam members24 at opposite sides of said oscillatory operating ring D.

Furthermore, cam members 25 are carried by opposite sides of saidoscillatory ring, and these cam members 25 cooperate with the cammembers 24 to positively shift the slidable pipe section 2i toward andaway from its companion pipe section 20, thereby clamping and releasingthe y sealing device C.

The housing is provided with internal abutments 26 and 2l, as shown inFigures 3 and 4, and the oscillatory operating ring is confined betweensaid abutments. so as to prevent or limit acting cams 24 and v2li insurethe desired forcible movements in both directions.

The separated flanges 23 may be integrally united with the pipe section2l, as shown most clearly in Fig. 6. However, the oscillatory operatingring can be made of separate segments (Figures 8, 9 and 10) to beassembled and united around the neck 22, so as to provide for location'oi' the ring between said flanges 23, while locating the cams on theouter side faces of the assembled segments. Figures 8, 9 and 10 clearlyshow a suitable ring wherein two pairs of semicircular-segments areunited by means oi screws to form the circular ring with cams 25 at itsopposite sides:

However, the oscillatory ring may be formed in any suitable manner, andany desired means may be employed to oscillate said ring. We areinclined to prefer a driving member extending from and connected to saidring under conditions which forcibly drive said ring in both directions.

For example, in Fig. 2 there is a screw threaded `driving member 23connected as shown at 23 to an extension of said oscillatory ring, anoperating nut rotatable on the screw thread oi said driving member tooscillate said ring, said operating nut being exposed at the exterior oithe housing, and means for preventing displacement oi said nut 30 in adirection longitudinally of said screw threaded driving member 2l. Inthisl form, the rotatable nut 30 has a flange 3l at the bottom conilnedby a bushing 32 screwed into thehousing, and after the desiredadjustment has been made, the nut 30 is anchored by a jam nut 33.

Special advantages are gained when this device is associated with anorice meter. For example, the detachable sealing device C may include anelongated oriiice member 3l with gaskets 35 at opposite sides of saidoriiice member. as shown most clearly in Figures 12, 13 and 14. Thiselongated orifice member 34 has upper and lower orices 3B and 31 ofdifferent diameters, and it can be readily removed and replaced in aninverted condition to selectively change the area of the orice lbetweenthe pipe sections. thereby varying the flow through the oriilce member.

Fig. 4 and Fig. 16 show pipes 33 'and 33 extending lfrom the pipesections at opposite sides of the orice member 34, and these pipes maybe connected to a meter as shown by the diagram in Fig. 17. Or, themeter 40 could be connected to widely separated portions of the pipesections 2l and 2l as suggested by the diagram in Fig. 18.

From another viewpoint, the convenient opening and closing oi' a pipecoupling as herein set forth is desirable in operations which require arapid change from a fully open connection to a blind" closure whichpositively prevents the transmission of iluid from one pipe section toanother. An illustration of this point appears in Fig. 15 wherein anelongated closure member 4l has an opening at its lower'portion toprovide for free ilow through the pipesections, and an upper portion toclose communication between the pipe sections when the member 4i isinverted.
